TCA chemical peel is a powerful peel to rejuvenate the skin, specially skin damaged by sun exposure.The healing process of a TCA chemical peel depends on the skin treated. The reason is the amount of skin appendages (small hair follicles) present in the skin. The skin of the face has a lot of appendages, therefore it heals in about 7 days after a peel. The neck and chest skin does have very few skin appendages, therefore healing process takes longer, usually weeks, and even months if a deep peel was performed.Patients post TCA chemical peel should adhere to post-chemical peel instructions given by their doctors to assure an smooth recovery and excellent outcome

this is devastating and looks like you were scarred and now have permanent redness and thinned skin.  I suggest seeing a cosmetic dermatologist for a formal consultation to see if anything can be done. this is very very hard to improve and likely needs skin care, vascular lasers.  Best, Dr. Emer.
